Answer:

Right side

Step-by-step explanation:

3x - 8 = 4(x + 5)

3x - 8 = 4x + 20

3x - 4x = 20 + 8

-x = 28 (divide both sides by -1)

x = -28

Answer:

x=-36

Step-by-step explanation:

I would start by distributing the right side first

4(x+5) is 4x+20.

That gives you 3x-8=4x+20

4x-3x=1x

-28-8= -36

x=-36
